4 Claims. 1

My invention relates to watch band terminals for wrist bands forwatches, and the object is to provide a terminal that will secure to theband a watch provided with rings or eyelets for attachment.

Another object of the invention is to provide the band with terminalshaving two relatively movable latching members, both actuated by thesame means.

In the appended drawing, forming part of this application,

Figure 1 is a section on line i-l, Figure 4,

showing the terminal in locked position;

Figure 2 is a similar section on line 22, Figure 3, showing the terminalopen;

Fi ure 3 is a section on line 3-3, Figure 1, in the direction of thearrow on the top of the figure;

Figure 4 is a section on line l l in the direction of the arrow at thebottom of the figure;

Figure 5 is an edge elevation of the liner;

Figure 6 is a, plan of the movable arm; and

Figure '7 is an edge elevation of same.

Referring to the drawings, a liner it formed of a plate having asemi-circular edge II, from which edge a fixed arm l2 extends co-planarwith the rest of the plate but disposed towards one side. The arm 52 onthe inner face and near the end thereof and towards the inward edge hasa flange l3 rising at right angles to the plane of the plate. Preferablythe outer surface of said flange I3 is fl sh with the edge from which itrises.

Pivoted on the inner face of the liner it with one end thereof is anL-shaped lever 14. The pivoted leg E5 of the lever is within the area ofthe arm l2 except of the pivot 16, which is located near the junction ofthe arm with the semicircular edge H. The other leg ll of the L- shapedlever extends through an opening is in the flange is. To properlycentralize the open? ing 58 with the leg H, a spacer I9 is providedbetween the end of leg :5 and the liner IE at the pivot H5.

The liner ii! has a collar 28 rising from the inner face thereof andconcentric with the semicircular edge ll of the liner it. See Figures 3,4, and 5. An arm 2! having the contour of the fixed arm 12 is providedwith an extension 22 ofiset laterally of the arm 2! to permit saidextension to lie on the outer face of the liner 5 5 with the arm 2|being directly opposite and co-planar with the fixed arm of the liner.See Figures 6 and 7.

The extension 22 has a bore 23 of the same diameter as the bore of thecollar 29 to accommodate a rivet 2 whereby the arm 2! is connectedpivotally to the liner in to swing to and from the fixed arm i2 alongthe semi-circular edge H. The swinging movement of the arm 2| on theliner I0 is limited by the engagement of a lug 25 rising from theextension 22 of the arm 2| with a slot 26 in the liner Ill, as best seenin Figures 1, 2 and 7.

The edge of the arm 2! proximate to the fixed arm 52 has a flange 2!similar to flange l3 on the arm l2 and in alinement therewith.The-flange 2'! is provided with an aperture 28 to receive the end 29 ofthe leg ll of the L-shaped lever M.

This end 29 has a notch 29 adapted to engage the inner face of theflange 21' of the swinging arm 2 I.

Mounted on the outside of the collar 20 is a helical spring 32, one end31' of which engages the lug 25 of the pivoted arm 2|, while the otherend 32 of the spring 30 engages a notch 33 in the leg 15 of the L-shapedlever M. The tendency of the spring 30 is normally to move the L-leverl4 and the pivoted arm 2| apart but prevented from so doing in theclosed position of' the terminal by the latching of the movable arm 2!with the L- lever I5.

The liner I 9 with its fixed arm l2 receives a cover or top 34, whichcover on the open side has notches (not shown) to engage and rest onshoulders 35 (see Figure 5), and the liner II! also has depressions 35,see Figures 1 and 2, to accommodate the tongues (not shown) by means ofwhich the cover is locked to the liner. A cover 3? is also provided forthe arm 2!, that is to say, that portion of the arm which extends pastthe curved edge of the liner H3. Said arm has at the end thereofshoulders 38 for engaging the corres onding notch in the open end of thecover 31.

The arm 2! has also depressions 39 to house the the arm. These tonguesare not shown in the drawing.

The liner In on the inner face thereof and near the straight edgesextending from the semi-circular portion thereof is provided with ears4!), substantially in alinement on an axis that is par allel to thestraight edge ii of the liner. The aperture 42 in the ears forms meansfor attaching the terminal to a band.

The terminal in closed position has the two arms i2 and 2! spanned bythe leg I! of the L- lever M. The notch 29' at the end 29 of the leg I!is engaged by the flange 2! through the aperture 28; see Figure 1. Toopen the terminal either to remove or to attach a watch to the terminal,the leg I I of the L-lever is pressed to move against the resistance ofthe spring 30, thus pivoting the L-lever M on the pivot 16 to disengagenotched end 29 of leg I! from flange 2! of the swinging arm 2|, therebypermitting the swinging arm 2| and the L-lever M to separate. See Figure2. In said figure the L-lever is shown in position when the notched end29 has just released the arm 2| by the disengagement of said notched end29 of the leg I! from the flange 27. The movement of the L-lever on thepivot l6 away from the s inging arm 2| is limited by the engagement ofthe leg I! with the edge of the aperture iii in the flange l3 near theend of the fixed arm l2.

To span the gap between the fixed arm l2 and the s inging arm 2| inclosing the teminal, the arm 2| is moved to engage the notched end 29 ofthe leg I! of the L-lever l4. bringing the ap-- ertured flan e 21 of thepivoted arm 2! into engagement with the notched end 29 of the leg H,which causes the said L-lever to move on its pivot l6 and bring thenotch 29' in latching position with the said flange 21 of the swingingarm.

I claim:

3. A band terminal comprising a liner having a fixed arm to one sidethereof and co-planar with the liner, a second arm pivoted to the linerto swing to and from the fixed arm and co-planar with said fixed arm,means for limiting the movement of said pivoted arm on the liner andproviding a gap between the arms, an L-shaped latch having one legthereof pivoted on the liner with the other leg extending from the fixedarm to the movable arm, said second leg having means for engaging themovable arm, a helical spring mounted on the liner and co-axial with thepivot of the movable arm, said spring having one end thereof engagingthe pivoted leg of the latch, while the other end of said spring engagesthe means for limiting the movement of the pivoted arm, said springnormally tending to move the pivoted arm and the latch apart, a coverfor said liner with the arm, and a cover for the pivoted arm.
